Pricing depends on your exact location.
Prices that are normal in my country may be rediculous in your country. I suggest you contact some local 'professionals', large companies, and see what they would charge.
One important thing to remember is that no sane company will hire you to do a pre-defined project on an hourly rate, they'll want a flat fee for the entire project.
If you agree an hourly price and you find out you need more time, they'll get nasty. Make good agreements about this before you start!
